## Questions & Answers

**Q: Will this fit a scirocco 2.0 tdi ?**
A: fit

**Q: Does this fit a ford fiesta zetec s 1.6 tdci?**
A: Hello, it is not suitable for ford fiesta zetec s 1.6 tdci, hope you can find the fittings for your car

**Q: Will this fit a golf gti mk4 1.8 turbo**
A: Yew it will. If you use it close as a diverter it holds boost better than the H,J factory diverter valve units. If you use it as an open expect a small boost delay as the air mass measured will not get back into the turbo intake. You will have slightly richer fuel but its safe. I found it a perfect fit for a K03s Hybrid boosting 1,6 - 1,8 bar, and able to hold the boost stable in reference to oem units in tapped [diverter] installation

**Q: Will this fit a astra sri 1.7 cdti?**
A: Hello, it applies to all 25mm accessories

To fit this on my car it would have taken alot more money and some major work.. it would fit the old style audi/vw engines fine but it was advertised to fit on my car which it clearly doesn't.
